New Delhi: Welcoming the Supreme Court verdict upholding the death sentence of Ajmal Kasab in the 26/11 Mumbai attacks case, BJP on Wednesday demanded execution of the Pakistani terrorist at the earliest.

"Those who wage war against the country and kill innocents deserve no mercy. ... Kasab should be hanged without any delay ... enough of biryani for him," BJP leader Mukhtar Abbas Naqvi told reporters here.

Describing Pakistan as "a terror factory", he said the government "must take all steps to destroy" terror infrastructure.

Naqvi also sought a separate set of laws to deal with terror-related cases.

"No leniency should be shown against this kind of a terrorist. They have tried to destroy the peace of the nation, so he (Kasab) should be hanged as fast as possible," he said.
